Calculates the new value in a weighted moving average series using the previous value and a weight range. The weight range is used to dynamically adjust based upon distance between the samples This allows you to smooth a value more aggressively for small noise and let large movements be smoothed less (or vice versa)
the next value in the series
template<typename T> static T DynamicWeightedMovingAverage ( T CurrentSample, T PreviousSample, T MaxDistance, T MinWeight, T MaxWeight )
